I think it has more to do with where you are when you attend one, if that makes sense. I attended the "I Can Do It" seminar in 2008. And, I attended Steve's CGW#2 so those are the only points of reference I have. ICDI was good but I wouldn't say I made any significant changes because of it. It was more like a re-affirming of my direction/belief type of thing. Steve's workshop, on the other hand, was a totally different experience. I would say that significant and lasting changes did result. I also think, however, that it was because I was already so strongly headed in that direction way before I ever got there. Also, Steve's workshop was comprehesive and all him rather than many topics/speakers like at ICDI. So, I'd say that seminars are the best thing you can do for yourself... when the timing is right and you are really ready for the changes to take place!
